The sequence of events for a null packet reception is as follows:
Receive operation initiated. The PHY indicates a receive
operation by asserting receive on the CTL lines. Normally, the
interface is idle when receive is asserted. However, the receive
operation may interrupt a status transfer operation that is in
progress so that the CTL lines may change from status to receive
without an intervening idle.
Data-on indication. The PHY asserts the data-on indication code
on the D lines for one or more cycles.
Receive operation terminated. The PHY terminates the receive
operation by asserting Idle on the CTL lines. The PHY shall assert
at least one cycle of Idle following a receive operation.
